Hello,

I am having issues trying to convert a federated subdomain to a managed subdomain while the root domain stays federated.
(fully written out problem by another user on stack overflow: https://stackoverflow.com/questions/69916859/whats-the-correct-microsoft-graph-api-endpoint-for-promoting-a-subdomain-to-roo)
Following the MS Docs here, it was possible to do so: https://learn.microsoft.com/en-us/azure/active-directory/enterprise-users/domains-verify-custom-subdomain.

But the documentation says you can use the Microsoft Graph API, however, the examples use http://graph.windows.net which is the soon to be deprecated Azure AD Graph API.
Some people on the feedback page also mention the same problem (https://github.com/MicrosoftDocs/azure-docs/issues?utf8=%E2%9C%93&q=%22f61490c2-0f18-4609-29f1-99ccb4215ad2%22&in=body).

Using the Microsoft Graph API, there is no way to promote the subdomain to a managed domain, while keeping the root domain federated.

Will this be added to the Microsoft Graph API? Or are there any alternatives?

    That operation is not supported via the Graph API afaik, only good old MSOnline PowerShell. As for any roadmap related question/feature requests, best post them on the Azure Feedback portal: https://feedback.azure.com/d365community/forum/22920db1-ad25-ec11-b6e6-000d3a4f0789
